PUMP.

SPECIFICATION forming part of Letters Patent No. 701,139, dated May 27, 1902.

Application filed January 6, 1902. Serial No. 881516- (No model To ctZZ 1071/0111/ t may concern:

Be it known that I, ORVILLE JESSE BRACK- NEY, acitizen of the United States, and a resident of Butler, in the county of Butler and 5 State of Pennsylvania, have invented a new and Improved Pump, of which the following is a full, clear, and exact description.

This invention relates particularly to improvements in pumps for removing sand,mud, or other heavy matter from oil, gas, and other wells; and the object is to provide a pump for this purpose of. simple construction and having no projections, such as collars or the like, on its outer side, so that it may be readily inserted in a well or withdrawn therefrom, and, further, to provide a simple means for fastening the inlet-valve inplace, whereby it may be easily removed or inserted with-` out the use of a pipe-wrench or similar tool.

I will describe a pump embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal section of a pump embodying my invention. Fig. 2 is a section on the line :c a: of Fig. 1, and Fig. 3 is a section on the line y @j of Fig. 1.

Referring to the drawings, 1 designates the pump tube or cylinder, having at a suitable point openings 2, through which liquid may be discharged as the pump is moved down to the bottom of a well. A piston or sucker 3 operates in the tube and has a stem or rod 4 extended upward through the cap 5, attached to the upper end of the tube. This sucker or piston 3 is provided with openings 6, through which material may pass upon a downward movement, and these openings are closed upon an upward movement of the sucker or piston by means of a plate-valve 7, mounted on the rod et.

Secured to the lower end of the tube 1 is a valve-casing 8. The upper portion of this Valve-casing, as clearly shown in Fig. 1, is reduced in diameter to fit snugly within the tube 1, so that the outer surface of the valvecasing will be flush with the outer surface of the tubef,and thus no proj ectionwill be made to interfere with the upward or downward movement of the pump. I have here shown the valve-casing as secured to the tube by means of rivets. It is to be understood, however, that the valve-casing is practically a continuation of the tube; but I prefer to make it as shown, so that it may be easily attached to a tube of any length or detached from a broken tube.

At the inner side the valve-casing has an annular shoulder 9, and below this annular shoulder the inner wall of the casing is tapered downward and outward. Removably placed in this portion of the valve-casing is a valve-supporting ring 10, the upper end of. which forms a seat for an upwardly-opening iiap-valve l1 of any suitable material. This ring 10 is tapered to correspond to the interior taper of the valve-casing, and the upper end is designed to abut against the shoulder 9. The ring is provided with an annular channel 11, adapted to' receive the inwardlyextended end 12 of a spring-plate 1'3. This spring-plate 13 is attached to the valve-casing and is seated in a longitudinal channel therein, so that its outer surface does not project beyond the outer surface of the casing. The lower inwardly-turned end 12 passes through an opening 14 in the casing, and above this opening a depression 15 is formed, into which a suitable instrument may be passed to engage against the inner side of the plate 13 to move it out ot' engagement with the valvesupporting ring. The valve-casing is also provided at one side with an opening 16, the aXialline of which is somewhat below the plane of the channel 11, so that when it is desired to remove the valve and the supporting-ring a suitable instrument may be passed through the opening 16 and engage with the lower wall of the channel 11a, while the instrument engages the upper wall of the open; ing 16. .Then after releasing the portion 12 from the ring it is obvious that by a lever motion of the instrument passed through the opening 16 the ring will be moved downward sufficiently to loosen it, so that it will fall by gravity or may be easily removed from the valve-casing.

The upper end of the stem or rod 4; is provided with a ring 17, to which a rod may be attached for operating the sucker or piston, and also on the rod or stem, within the tube 1, is a collar 18, which is somewhat above the valve 17, and this collar 18 is designed to engage with the cap 5 when the pump is to be withdrawn from a well.

In operation the pump is to be lowered into the well and to the bottom thereof. The water or other liquid passing into the. pump (it being understood at this time that the sucker or piston will be above the openings 2) will pass out through said openings and back into the well. When in its lowered position, the

sucker or pistou is to be moved downward.

Then upon an upward movement the sand, mud, or the like, with a certain amount of liquid, will be drawn upward, opening the valve 11. Then upon again moving the piston downward the liquid or other material will pass through the openings 6, and the valve 11 will be closed. Upon the upward movements it is obvious that the valve 7 will close the several openings 6.-

It will be noted in Fig. 1 that the lower end of the valve-casing is made in the form of legs, so that material may pass through the spaces between the same.

After ehargingor practically filling the pump with sand, mud, or the like it is to be withdrawn and the valve 1l, with its supporting-ring, removed in the manner beforeV described, and then the material may bei easily emptied from the pump.

Having thus described my invention, Iv

claim as new and desire to secure by Letters Patent- 1. A pump comprising a tube, a ring arranged in the lower portion of the tube and forming a valve-seat, a valve supported on the ring, an annular channel formed in the outer surface of the ring, the tube being pro-i vided with an opening in line with said chau` nel and an opening having its aXial line below the plane of the channel, and a springplate attached to the tube and having an in' wardly-turned end for passing through the first-named opening and into the channel, substantially as specified.

2. A pump comprising a tube having aninterior annular shoulder near its lower end, the said tube below said shoulder being tapered downward and outward, a valve-supporting ring correspondingly tapered at its outer side and adapted to engage its upper end against said shoulder, a valve supported on the ring, an annular channel formed in the outer surface of the ring, the tube being provided with an opening in line with said channel, and an opening having its axial line below the plane of the channel, a spring-plate attached to the tube and having an inwardlyturned end for passing through the firstnamed opening and into the channel, and a sucker operating in the tube, substantially as specified.

3. In apump, atube, a valve-casingsecured to the lower end of said tube and having its outer surface flush with the tube, the said casing being provided with an annular shoulder and tapered downward and outward from said shoulder,a valve-supporting ring tapered on its outer side to t said taper of the casing, the said ring having an annular channel, a valve on the upper end of the ring, the valve-@asin g bein g provided with an opening in line with the channel of the ring and also with an opening on a lower plane than the channel, a spring-plate seated in a recess formed in the casing and having an inwardlyturned portion for passing through the rstnamed opening and into said channel, the said casing also having a depression or recess above the first-named opening, whereby an instrument may be inserted against the inner side of the plate, and a sucker for operating in the tube, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
